Comprising all those atid (a) p. 1, which are from 500 to 1000 
Seographical miles distant from the magnetic pole; the second, 
those marked (6), which are from 1200 to 1500 miles distant ; 
and the third, those marked (c), including the great majority of 
Slations in the United States, which are from 1600 to miles 
tant, from the same point. Lake Athabasca, contrary perhaps 
to first impressions, is the nearest permanent station to this as- 
sumed centre of influence. Fort Confidence, which is not a per- 
Manent station, is of course nearer—but Fort Simpson and the 
patie posts on McKenzie’s River, notwithstanding their northerly 
Position, are somewhat more distant. 
(a) Commencing on the 19th. (6) Down to the 1ith. (c) Down to the 10th.
